Liquid battery could charge green energy
- Engineering professor Donald Sadoway on Thursday used an old-school chalk board at the prestigious TED gathering to write the formula for a liquid battery that could one day cut the need for new power plants."The way things stand, electricity demand must be in constant balance with supply," Sadoway told the tech-savvy audience in southern California.Inexpensive batteries made from liquid metal could store electricity from solar panels, wind farms, or existing generation facilities and save it for when it is most needed.That would be a major change from today's consume-it-now-or-lose-it systems."The battery is the enabling device here," he said. "With it we could draw electricity from the sun even when the sun doesn't shine."Sadoway and his team of students at Massachusetts Institute of Technology were so confident in their creation that they started Liquid Metal Battery Corporation and plan to have bistro-table size models out in two years.Microsoft co-founder Bill Gates is among the company's backers.
